Trump picked his transition chairman and other leaders on Friday. It's his biggest staffing announcement since he won the election this week.

Christie will now serve as vice chairman. He's joined on the executive committee by former House Speaker Newt Gingrich, retired neurosurgeon Ben Carson, Lt. Gen. Michael Flynn, former New York Mayor Rudolph Giuliani and Alabama Sen. Jeff Sessions.

A statement says more than a dozen other people will also advise Trump on transition matters. They include some of Trump's children, Republican Party Chairman Reince Priebus and former Breitbart news executive Steve Bannon.

President-elect Donald J. Trump said in a statement: “The mission of our team will be clear: put together the most highly qualified group of successful leaders who will be able to implement our change agenda in Washington. Together, we will begin the urgent task of rebuilding this nation - specifically jobs, security and opportunity. This team is going to get to work immediately to Make America Great Again.”
